How does unused motor oil affect the percent germination of Romaine Lettuce (Lactuca sativa L. var. longifolia) seeds? Research Question How does unused motor oil affect the percent germination of Romaine Lettuce (Lactuca sativa L. var. longifolia) seeds? Background Germination in seeds is when the seed coat breaks revealing the embryo or sprout of the plant (Biology Online). For a seed to properly germinate it must have water, oxygen, and the correct temperature (BBC). Each type of seed has a specific range of conditions like temperature, amount of water and light that will allow them to germinate (BBC). To germinate Romaine (Lactuca sativa L. var. longifolia) seeds, the temperature of the seeds cannot reach above 30 °C (Heirloom). It…

Does the weight of a seed affect how fast a plant grows? A seed is “the fertilized, matured ovule of a flowering plant, containing an embryo or rudimentary plant.” (Dictionary.com) Seeds go through a process, called germination, to grow. The seed first has its roots break out and grab hold of the soil. After the roots have a hold of the soil a small plant will sprout from the ground. All plants go through the germination process. (How do Seeds Sprout?) The hypothesis is: If the weight of a…

plant grows out from a seed. The most common example is the sprouting from a seed of an angiosperm, a flowering plant, or a gymnosperm that are seed-bearing plants. For a seed to germinate, few external conditions are in need to be met as well as internal conditions of the seed such as its dormancy, viability and its vitality to sprout. When these internal conditions are met, the external conditions at the time of seed germination plays a big role. First of all, enough water is needed. It is…

Germination of Brassica rapa Seeds Germination is a vital stage in a plants life, but it also plays a significant role in other animals’ (including humans) life cycle. It is the process in which a new plant grows from a seed. Due to the fact that plants are autotrophs; they use the process of photosynthesis to transform sunlight and make their own food. Germination occurs in gymnosperms and angiosperms when the seed is using its own nutrients, before it is able to photosynthesize. “The plant’s…

Hydrogen Peroxide Help or Harm Seeds? Hydrogen peroxide (H2O2) is a common household item. It is made of two hydrogen atoms and two oxygen atoms. It is most commonly used in small concentrations to clean small cuts and scrapes by killing bacteria. This antiseptic kills the bacteria by tearing down their cell walls. In the last few years, hydrogen peroxide has been added to pesticides. This means that the food we consume has been growing in materials that contain hydrogen peroxide. We have a…

interested at the same time for me. I wanted to see which bag of radish seeds will grow when it was inserted inside a microwave. This experiment looks interseted because i wanna see what would happen to the seeds as soon as they last 10 seconds inside the microwave. This can be a good project for others it looks preety cool, it can be used in the REAL WORLD. There are people who plant these Radish Seeds and put them in the ground were it can get enough sun and they can water the seeds. The…

experiment is about the effect of microwave radiation exposure on the percent that radish seeds germinate. The hypothesis in this experiment is if the radish seed is placed in the microwave for 8 minutes, then the percent of germinated seeds would be the lowest out of all the times. This experiment is important because if something happens and radish seeds are exposed to microwave radiation people would be able to know if the radishes would germinate if they knew the time they were exposed. This…

Nine of the Burpee Pea Seeds were tested with tap water that had a pH 8 and nine were tested with a lemon juice and water solution that had a pH of 4. of Between days one through four the acid rain and tap water seeds were alike. The seeds were round and tan. On day two the seed coat became squishy. On day three test one seeds two and three of the acid rain and water began to sprout roots, and all of the seeds in test two and three began to sprout. Seeds one, two, and three in the acid rain…

lentil bean seeds was affected by the environmental aqueous solutions, which was made up of either a table sugar, dextrose or a control. It presented that there was not a statistical difference between the table sugar or dextrose aqueous solutions in comparison to the radicle lengths since the P values were less than 0.05. Although, there was a statistical increase in radicle length with the comparison to the control. If these seeds were able to reach the average seed germination process in ten…

Introduction/Purpose There are many parts to a seed. First, there is the testa (seed coat). It is the outside layer protecting the inside of the seed. On the side of the seed, there is a tiny hole called the micropyle. Water can be taken through the hole when it is ready to germinate. Inside the seed near the micropyle, there is a root called a radicle. When the seed begins to grow the radicle will come out the micropyle. The seed coat can protect the seed from many factors such as…
